T 0 all whomit may :01 were I Be it known thatj, Fnn rBoNsnR, a citiapivoted lever to close the jaw and by a return acting spring to open thejaw; and the objects of my invention are first, to provide a simplyconstructed grasping instrument that will grasp and hold and lift areceptacle without injuring or scratching it; second, will enable theoperator to lift a jar of boiling fruit from a container or stovewithout injuring the jar or spilling its contents; third, will enablethe operator to pick up any common culinary article from the stove orfrom the tire without injuring the article, or dropping it: fourth, willenable the operator to apply only such grasping force as will hold thearticle grasped without exerting enough force to crush it; and otherobjects that will appear in this specification.

I attain these objects by means of'the mechanism illustrated in theaccompanying drawing, in'which Figure 1, is a plan view of one side ofthe instrument; Fig. 2, is a plan view of the under side of Figure 1;and Fig. 3, is a detail of the pivotal connection of he hand-oper atedlever and plunger.

Similar numerals refer to similar parts throughout the several views.

The stalk 1, of this instrument may be made of metal, wood orcomposition, and is provided with a metal front jaw 2. extendingdownwardly at an obtuse angle from said stalk 1, and integral therewith.

The pivoted lower j '3, is operated forwardly so as to engage the frontjaw, by means of a plunger pin 4. actuated forwardly by the handle lever55, and said jaw 3, and said pin 4, are actuated backwardly to theirnormal positions by means of the coil sprin 6, pressing outwardlyagainst the collar 1, which is integral with said pin 4. and against theabutment 8, which is integral with said stalk 1.

In using "this grasping instrument the operator takes hold of the stalkat end oppositesaid jawsandwhen hehas caused said jaws to inclose thearticle, to hexgrasped, as

the edgeof a dish, as represented by the "sec-v ti onal part of a metalpan shown at A, in F g. Lhegrips the handle lever 5, which is pivoted tothe stalk l at 9, and compressing it throws the integrallever 10,forward,

forcingthe plunger pin forward against the lower aw 3, at 11, thuscausing aw?) to move torward against A, and 2, by reason of beingpivoted at 12. In compressing the lever 5, against the stalk 1, theplunger pin l, is slid along throughthe hole 13,. in the abutment 8, andwhenthe hand pressure is released by the operator from the handlever 5,the coil spring 6, forces said plunger pin back and as it is pivoted at14:, to the jaw 3,

it too is drawn baekwa'rdly andopens the space between jaws 2 and 3, andthus re-,

leases the article grasped. At 15;, and 16,

are shown facings of pliable materialfas asbestos, securedto the contactpart of said.

jaws for the purpose of avoiding scratching or marring the articlesgrasped.

Having thus describedmy invention in this grasping instrument; I claiml. A grasping instrument comprismg in combination, a "stalk, extendingthe whole length of the instrument; a jawomember at one end of saidstalk and integral therewith and extending at an angle of about fortyfive degrees from the line of extension of said stalk; a separate jawprovided to oppose said integral jaw and to register therewith andpivota'lly securedat its upper end to the under side of said stalk; aplunger pin pivotally secured at its forward end to said separatepivotally securedj aw to operate it against said integral jaw; a bellcrankpivoted on said stalk on its under sidelnear its longitudinalcenter with its longer lever extending longitudinally with said stalk toits end and its short lever extending toward said stalk, the end of saidshort lever being pivotally securedto the opposite end of said plungerpin from said pivoted jaw; a coil spring surrounding said plunger pinand normally forcing it toward said bell crank,

thus drawing said pivotally suspended jaw;v

from said integral jaw, and soft cushions on 9 the faces of said aws,forthe purposes specitied,

dle, a pair of graspingjawsoperatively con-v nected at oneend of saldhandle, one of said 2. A graspinginstrument of the class de, .scribed,comprising 111 combination, a hanjaws being integral with the end ofsaid handle and the other said jaw being pivotally mounted at one endupon said handle near the other jaw, a graspable lever pivotally securednear the middle of said handle and its swing end extending to the end ofthe handle and slidably connected therewith, a projecting lug integralwith said lever and extending inwardly from its pivotal point towardsaid handle, a plunger pin connecting said inwardly projecting lug andsaid pivotally mounted jaw tavings 01F pliable nonabrasive materialmounted on the contact faces of said jaws, causing them to work inunison, a housing in said handle enclosing said plunger pin, and a coilspring mounted about said plunger pin and normally actuating it awayfrom said integral jaw.
